CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to Taiwan application 105209923, filedJun. 30, 2016, the entire contents of which are incorporated herein byreference for all purposes.

TECHNICAL FIELD

The present disclosure relates to a waistband and more particularly to aporomeric waistband.

BACKGROUND

When a person's waist is injured or the person is required to stand fora long duration, a waistband is often used for increasing the support ofthe waist and protecting the waist from further injury. Therefore, thewaistband is used for providing a protection and support effect.

However, conventional waistbands are mostly made of woven fibers withpoor elasticity and support. They can only provide a very weak effectfor the users. Fibers have poor air permeability. Therefore, after along duration of usage or under high temperatures, the waist will sweatand feel very hot to cause discomfort to the users.

SUMMARY

A poromeric waistband embodying aspects of the present inventioncomprises a waistband composed of an elastic colloid sheet and aporomeric supporting portion protrudingly disposed on a side of thewaistband. The poromeric supporting portion comprises a plurality ofsupporting ribs disposed roughly perpendicular to the waistband andventilating passages formed between the supporting ribs. The waistbandfurther comprises a fastening unit disposed on two ends of the waistbandrespectively, and the waistband is formed as a loop by overlapping thetwo fastening units on the two ends.

The colloid of the waistband of the poromeric waistband embodyingaspects of the present invention provides an excellent elasticity for agood wrapping effect for the users. The supporting ribs of the poromericsupporting portion provide an anti-slipping and supporting effect. Theventilating passages between the supporting ribs provide an aircirculation effect for maintaining the users' comfort even under longduration of usage and high temperatures.

Aspects of the present invention will become more fully understood byreference to the following detailed description thereof when read inconjunction with the attached drawings.

DETAILED DESCRIPTION

Please refer to FIGS. 1 and 2. FIGS. 1 and 2 are perspective and frontviews of a preferred embodiment of a poromeric waistband, or belt, ofthe present invention respectively. The poromeric waistband mainlycomprises a waistband 10 and a fastening unit 30.

The waistband 10 is composed of an elastic colloid sheet. The colloid ismade of latex, silicone rubber, rubber or other elastic colloids. Pleaseto FIG. 3. FIG. 3 is a back view of the preferred embodiment of theporomeric waistband of the present invention. The colloid is mixed withfunctional powder 20. The functional powder 20 is bamboo charcoal powder21 or other kinds of functional powder such as far infrared powder andantibacterial powder. A poromeric supporting portion 11 is protrudinglydisposed on a side of the waistband 10. The poromeric supporting portion11 comprises a plurality of supporting ribs 111 disposed roughlyperpendicular to the waistband 10. The supporting ribs 111 are serrated,wavy or straight in shape. Ventilating passages 112 are formed betweenthe supporting ribs 111. A plurality of ventilation holes 12 ispenetratingly disposed on the waistband 10. In an embodiment, thecolloid sheet comprises a gel.

The fastening unit 30 is composed of, for example, hook and loopfastener 31 (e.g., Velcro). A portion of the hook and loop fastener 31is disposed on one end of the waistband 10 while a mating portion isdisposed on the other end. The waistband 10 is formed as a loop byoverlapping the two fastening units 30 on the two ends.

In order to further explain the structures and characteristics of thepresent invention, as well as the technical means and expected effects;the ways of usage are specifically described hereunder for in-depthunderstanding.

Please refer to FIGS. 1, 2 and 3. When using the waistband 10, simplysurround the waist of a user with the waistband 10. Then, join thefastening units 30 on the two ends of the waistband 10 together to makethe fastener 31 to stick and fasten together so that the user's waist issecurely surrounded by the waistband 10. The colloid of the waistband 10provides an excellent elasticity for a good wrapping effect. Thesupporting ribs 111 of the poromeric supporting portion 11 provide ananti-slipping and supporting effect. The ventilating passages 112between the supporting ribs 111 provide a vertical air circulationeffect, and the ventilation holes 12 allow the air current to penetratethrough the waistband 10 for maintaining the user's comfort even underlong duration of usage and high temperatures. The colloid is mixed withthe functional powder 20 for allowing the waistband 10 to generate farinfrared or antibacterial effect. Therefore, the function of thewaistband 10 is enhanced or the lifespan is prolonged.

Please refer to FIG. 4. FIG. 4 is a front view of another preferredembodiment of the poromeric waistband of the present invention. Anauxiliary supporting sheet 13 is extended from upper and lower sides ofthe waistband 10 respectively. The poromeric supporting portion 11 isalso extended on the auxiliary supporting sheets 13. The auxiliarysupporting sheets 13 provide more wrapping area for the waist forenhancing the supporting effect. The poromeric supporting portion 11also provides supporting and ventilating effects on the auxiliarysupporting sheets 13.

Note that the specifications relating to the above embodiments should beconstrued as exemplary rather than as limitative of the presentinvention, with many variations and modifications being readilyattainable by a person of average skill in the art without departingfrom the spirit or scope thereof as defined by the appended claims andtheir legal equivalents.
